When the quiet but sharp-tongued Kim Sunoo is forced to sit beside the new transfer student, Park Sunghoon, his peaceful school life crumbles overnight. Sunghoon is everything Sunoo can't stand-arrogant, cold, and infuriatingly perfect at everything he does. From classroom arguments to after-school clashes, the two become locked in a battle of pride, neither willing to back down. But between the sharp words and colder glares, something begins to shift. A spark hidden beneath the rivalry turns into stolen glances, accidental touches and a tension neither of them can explain or resist. In a world where love is the last thing they wanted, Sunoo and Sunghoon must face the truth: sometimes the line between hate and something deeper is thinner than they ever imagined.

Kim Sunoo and Park Sunghoon have always been neck-and-neck-top grades, top rankings, top rivals. To everyone else, they're sworn enemies, constantly trying to outsmart, outshine, and outdo each other. But behind closed doors? Let's just say "top of the class" isn't the only thing they're competing for. What starts as late-night study sessions filled with snark and bickering slowly unravels into something messier, softer, and infinitely more dangerous: feelings neither of them can afford to have. After all, there can only be one at the top... right? Warning this will contain lots of cussing and mature scenes so read at your own risk! Rankings: #1 sunsun
